Hunhu hwezvicherwa uye chimiro chezvicherwa
Zvicherwa zvine titanium zvinosanganisira ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, nezvimwewo, pakati pazvo ilmenite nerutile ndiwo mamineral makuru ekunyungudutsa titanium.
Fomura yemamorekuru yeilmenite iFeTiO3, ine 52.66% yeTiO2 uye 47.34% yeFeO. Isimbi ine grey kusvika kudema, ine kuomarara kweMohs kwe5-6, density ye4.72g/cm3, medium magnetism, good conductor, uye normal type. Quotation yemhando inosanganiswa nemagnesium nemanganese, kana kuti ine fine scaly hematite inclusions.
Fomura yemamorekuru yerutile iTiO2, ine 60% Ti uye 40% O. Iminerali yakatsvuka-tsvuku, inowanzova nemusanganiswa wesimbi, niobium, chromium, tantalum, tin, nezvimwewo, ine kuomarara kweMohs kwe6, uye density ye4.2~4.3g/cm3. Magnetism, conductivity yakanaka, brown yakasviba kana iron yakawanda, rutile inonyanya kugadzirwa muma placers.
Minda yekushandisa uye zviratidzo zvehunyanzvi
Rutile neilmenite ndizvo zvinhu zvikuru zvinoshandiswa pakunyungudutsa titanium yesimbi, kugadzira titanium dioxide, welding rods, uye welding fluxes.

Tekinoroji yekugadzirisa
Kazhinji ilmenite nerutile ore zvinoperekedzwa nezvimwe zvicherwa zvakasiyana-siyana, zvakaita semagnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene. Matombo, nezvimwewo, anowanzo sarudzwa nekupatsanurwa kwegiravhiti, kupatsanurwa kwemagineti, kupatsanurwa kwemagetsi uye kutenderera kwemvura.
Kubatsira kwesimba regiravhiti
Nzira iyi inowanzo shandiswa pakupatsanura rough placer ine titanium kana primary ore yakapwanywa ine titanium. Huwandu hwezvicherwa zvine titanium hunowanzo pfuura 4g/cm3. Nokudaro, magangue mazhinji ane huremu husingasviki 3g/cm3 anogona kubviswa nekupatsanura gravity. Kubvisa mineral. Midziyo yekupatsanura gravity inosanganisira jig, spiral concentrator, shaker, chute, nezvimwewo.
Kupatsanurwa kwemagineti
Nzira yekuparadzanisa magnetic inoshandiswa zvakanyanya mukusarudza zvicherwa zvine titanium. Tinogona kushandisa kupatsanura magnetic isina simba kuparadzanisa magnetite, tobva tashandisa kupatsanura magnetic yakasimba kuparadzanisa ilmenite yepakati-magnetic. Semuenzaniso, concentrate ine iron oxide yakawanda kana kuti. Kune iron silicate, nzira yekuparadzanisa gravity inofanira kushandiswa kubvisa tsvina ine diki specific gravity. Muindasitiri, kushandiswa kwemagnetic yakaoma uye yakanyorova. Magnetic separation zvishandiso zvinosanganisira cylindrical magnetic separator, plate magnetic separator, vertical ring high gradient magnetic separator, nezvimwewo.
Dhiramu remagineti rinopatsanura
Plate yemagineti ine simba guru
Kubatsira kwemagetsi
Inonyanya kushandisa musiyano we conductivity pakati pezvicherwa zvakasiyana mu titanium-concentrate coarse concentrate pakusarudza, zvakaita sekupatsanurwa kwe rutile, zircon, uye monazite. Zviparadzanisi zvemagetsi zvinoshandiswa ndezviya zve roller type, plate type, sieve plate type nezvimwewo.
Kuyangarara
Inonyanya kushandiswa kuparadzanisa matombo ane titanium akacheneswa zvakanaka. Zvinhu zvinoshandiswa pakudonha matombo zvinosanganisira sulfuric acid, tall oil, oleic acid, diesel oil uye emulsifiers. Nzira dzekuvandudza matombo dzinosanganisira kudonha matombo etitanium zvakanaka uye kudonha matombo egangue.
Kubatsirana kwenhengo
Kune placerite ine zvicherwa zvakawanda zvine chekuita nayo, musiyano uripo pakati pesimba remagineti, density, conductivity, uye floating pakati pezvicherwa unogona kushandiswa kupatsanura zvicherwa nemaitiro akabatanidzwa e "magnetic, heavy, electric, uye float". Semuenzaniso, jecha regungwa rine zvicherwa zvakaita semagnetite, ilmenite, rutile, zircon jecha, monazite, sea jecha, nezvimwewo. Kutanga, magnetite inopatsanurwa nesimba remagineti risina simba, uye ipapo ilmenite inopatsanurwa ne vertical ring ine medium field strength. Ring yakasimba ye vertical strength ye vertical ring tailings inobvisa zvimwe zvicherwa zvine iron, uye ipapo diki specific gravity inopatsanurwa nenzira yekupatsanura gravity. Kune jecha regungwa, zvicherwa zvinorema i rutile ne zircon jecha. Rutile ine conductivity iri nani inogona kusarudzwa nekupatsanura electric, kuitira kuti kupedzisa kupatsanurana kunoshanda kwerudzi urwu rwe mineral.
Mhete yakatwasuka ine gradient yakakura yemagineti inoparadzanisa
Nyaya yekubatsira
Kune magnetite, titanomagnetite, ilmenite, rutile, jecha rezircon, jecha regungwa uye zvicherwa zvishoma zvine iron mu alluvial placers muIndonesia.，Pakati pazvo, ilmenite, rutile, uye zircon jecha ndizvo zvicherwa zvikuru, uye titanomagnetite, iron oxide, iron silicate, uye sea jecha zvinhu zvisina kuchena. Zvicherwa zvinopatsanurwa uye zvinotsanangurwa nenzira dzepanyama dzakadai sekupatsanurwa kwemagineti uye kupatsanurwa kwegiravhiti. Zvese zvigadzirwa zve concentrate. Pakati pazvo ilmenite, rutile, zircon ndizvo zvicherwa zvikuru, ilmenite, iron oxide, iron silicate, sea jecha setsvina, Kuburikidza nekupatsanurwa kwemagineti, kupatsanurwa kwegiravhiti nedzimwe nzira dzepanyama, zvicherwa zvinopatsanurwa uye zvigadzirwa zve concentrate zvinosarudzwa.
Hukuru hwejecha realluvial hwakafanana, uye hukuru hwese hwezvinhu izvi hunosvika 0.03 ~ 0.85 mm. Zvigadzirwa zve concentrate zvine hunyanzvi zvakaita se ilmenite, rutile ne zircon jecha zvinopatsanurwa ne combined beneficiation process yekuparadzanisa kwemagnetic isina simba + medium magnetic separation + high magnetic separation + gravity separation.
